COVERING SPECIFICATIONS 503
(c) Use cork fitting jackets on all screwed fittings up to and
including 5-inch, and on all flanged fittings up to and including 4-inch.
On all larger sizes use cork segments.
Ice Water and Cold Lines Operating Above 25° F.—Note: Follow
same specifications as given for Brine Thickness cork pipe covering,
except:
(a) Substitute Ice Water for "Brine."
(b) Use sectional covering on all pipe lines up to and including
10-inch nominal pipe size, and segmental covering on larger sizes.
(c) Use cork fitting jackets on all screwed fittings up to and
including 6-inch, and on all flanged fittings up to and including
4-inch. On all larger sizes use cork segments.
Cylindrical Tanks Operating at Various Temperatures.—
Below 5° F. use one layer 6-in. cork lags.
5° to 20° F. use one layer 5-in. cork lags.
20° to 32° F. use one layer 4-in. cork lags.
Z2° to 55° F. use one layer 3-in. cork lags.
55° F. and up use one layer 2-in. cork lags.
Cover the cylindrical tank operating at from ....° to ....° F.,
after it has been tested, cleaned and approved, with .... inch thick
cork lags and discs weighing approximately 1.25 lbs. per board foot
and having a mineral rubber finish ironed on at the factory on both
the inner and outer surfaces.
Insulate the cylindrical surface of the tank with one layer of cork
lags beveled to the proper radius. Insulate any and all flanges of the
tank with one layer of cork lags projecting beyond the heads of the
tank the equal of the thickness of the discs and applied so as to
have a bearing of at least one foot on the lags of the body of the
tank. (If either head of the tank has no flange, extend the body
lags beyond the end of the tank the equal of the thickness of the
disc.)
Apply body and flange lags with waterproof cement on all joints,
and secure in place with 1-inch bands (or l]^-inch bands) of not
lighter than No. 26 gauge brass drawn up tight by means of bolts
and clips riveted to the ends of the bands. Space these bands not
more than one foot apart for body lags and use not less than three
for lags on each flange.
Apply discs directly against the heads of the tanks, and hold in
place by means of flange or body lags as the case may be. Fill all
spaces between the tank heads and the discs with regranulated cork
well packed.
Build boxes of tongued and grooved boards around the supports
on which the tank rests, so as to leave from four to six inches of
space on all sides, and fill these spaces with regranulated cork well
packed. (To obviate the necessity of boxing in the tank supports and
